One of the more durable types of roof, a slate roof is also one of the most beautiful. However, its also one of the most expensive types of roofs to install. Repairs like flashing rand tile replacing tiles or fixing fasteners due to harsh weather conditions can be a factor.
In most cases you will need to rely on a slate shingle professional for these repairs. Because these materials are so heavy to deal with, there is serious risk of personal injury if you try to DIY repairs. Slate roofs can cost $1,000 to $2,000 per square ft. to install, more than most types of roofing, possibly with the exception clay tile, but can last 2 to 4 times longer than most. Many current “slate” products are composite shingles, which look like slate but are available at a much lower price and are lighter weight.
